MVPLoginDemo
1.IView View层
package com.example.lenovo.logindemo02.view; import android.content.Context; /** * */ public interface IView{ void success(T t); void failed(Exception e); String getMobile(); //p层验证用 String getPassword(); void setMobile(String mobile); void setPassword(String password); void check(boolean isChecked); void show(); void dissmiss(); void gotoMain(); Context getContext(); }
/ /MainActivity
package com.example.lenovo.logindemo02.view; import android.app.ProgressDialog; import android.content.Context; import android.content.Intent; import android.support.v7.app.AppCompatActivity; import android.os.Bundle; import android.view.View; import android.widget.Button; import android.widget.EditText; import android.widget.TextView; import android.widget.Toast; import com.example.lenovo.logindemo02.R; import com.example.lenovo.logindemo02.bean.LoginBean; import com.example.lenovo.logindemo02.presenter.LoginPresenter; public class MainActivity extends AppCompatActivity implements IView, View.OnClickListener { private EditText edtMobile; private EditText edtPassword; private Button btnLogin; private TextView txtZhuce; private LoginPresenter presenter; private ProgressDialog pd; @Override protected void onCreate(Bundle savedInstanceState) { super.onCreate(savedInstanceState); setContentView(R.layout.activity_main); initView(); initData(); } private void initData() { presenter = new LoginPresenter(); presenter.attach(this); presenter.isFirst(); pd = new ProgressDialog(this); pd.setMessage("正在登录,请稍后..."); } private void initView() { edtMobile = findViewById(R.id.edt_mobile); edtPassword = findViewById(R.id.edt_password); btnLogin = findViewById(R.id.btn_login); txtZhuce = findViewById(R.id.txt_zhuce); btnLogin.setOnClickListener(this); } @Override public void success(LoginBean loginBean) { if (loginBean != null){ Toast.makeText(this, loginBean.getMsg(), Toast.LENGTH_SHORT).show(); } } @Override public void failed(Exception e) { Toast.makeText(this,e.getMessage(),Toast.LENGTH_SHORT).show(); } @Override public String getMobile() { return edtMobile.getText().toString().trim(); } @Override public String getPassword() { return edtPassword.getText().toString(); } @Override public void setMobile(String mobile) { edtMobile.setText(mobile); } @Override public void setPassword(String password) { edtPassword.setText(password); } @Override public void check(boolean isChecked) { if (isChecked){ presenter.login("https://www.zhaoapi.cn/user/login"); } } @Override public void show() { pd.show(); } @Override public void dissmiss() { pd.dismiss(); } @Override public void gotoMain() { Intent intent = new Intent(MainActivity.this,HomeActivity.class); startActivity(intent); finish(); } @Override public Context getContext() { return this; } //点击 @Override public void onClick(View view) { switch (view.getId()){ case R.id.btn_login: presenter.check(); break; } } @Override protected void onDestroy() { super.onDestroy(); if(presenter != null){ presenter.detach(); } } }
2. Model层
public class LoginModel {
public void login(String url, ICallBack callBack , Type type){
HttpUtils.getInstance().get(url,callBack,type);
}
}
2.1 HttpUtils
package com.example.lenovo.logindemo02.utils;
import android.os.Handler;
import com.example.lenovo.logindemo02.inter.ICallBack;
import com.google.gson.Gson;
import java.io.IOException;
import java.lang.reflect.Type;
import okhttp3.Call;
import okhttp3.Callback;
import okhttp3.OkHttpClient;
import okhttp3.Request;
import okhttp3.Response;
/**
*
*/
public class HttpUtils {
private static volatile HttpUtils instance;
private OkHttpClient client;
private Handler handler = new Handler();
private HttpUtils(){
client = new OkHttpClient();
}
public static HttpUtils getInstance(){
if (instance == null){
synchronized (HttpUtils.class){
if (null == instance){
instance = new HttpUtils();
}
}
}
return instance;
}
public void get(String url, final ICallBack callBack, final Type type){
Request request = new Request.Builder()
.get()
.url(url)
.build();
Call call = client.newCall(request);
call.enqueue(new Callback() {
@Override
public void onFailure(Call call, final IOException e) {
handler.post(new Runnable() {
@Override
public void run() {
callBack.onFailed(e);
}
});
}
@Override
public void onResponse(Call call, Response response) throws IOException {
String result = response.body().string();
Gson gson = new Gson();
final Object o = gson.fromJson(result, type);
handler.post(new Runnable() {
@Override
public void run() {
callBack.onSuccess(o);
}
});
}
});
}
}
2.2 ICallBack
package com.example.lenovo.logindemo02.inter;
/**
*
*/
public interface ICallBack {
void onSuccess(Object obj);
void onFailed(Exception e);
}
3. Presenter层
package com.example.lenovo.logindemo02.presenter;
import android.content.Context;
import android.content.SharedPreferences;
import android.text.TextUtils;
import com.example.lenovo.logindemo02.bean.LoginBean;
import com.example.lenovo.logindemo02.inter.ICallBack;
import com.example.lenovo.logindemo02.model.LoginModel;
import com.example.lenovo.logindemo02.view.IView;
import com.google.gson.reflect.TypeToken;
import java.lang.reflect.Type;
/**
*
*/
public class LoginPresenter {
private IView iv;
private LoginModel loginModel;
public void attach(IView iv){
this.iv = iv;
loginModel = new LoginModel();
}
public void detach(){
if (iv != iv){
iv=iv;
}
}
//检验
public void check(){
if (TextUtils.isEmpty(iv.getMobile()) || TextUtils.isEmpty(iv.getPassword())){
iv.check(false);
}else {
iv.check(true);
}
}
public void isFirst(){
SharedPreferences sp = iv.getContext().getSharedPreferences("config", Context.MODE_PRIVATE);
String mobile = sp.getString("mobile", "");
String password = sp.getString("password","");
//不是第一次登录
if (! TextUtils.isEmpty(mobile) &&!TextUtils.isEmpty(password)){
iv.setMobile(mobile);
iv.setPassword(password);
}
}
public void login(String url){
iv.show();
final String mobile = iv.getMobile();
final String password = iv.getPassword();
url = url.concat("?mobile=").concat(mobile).concat("&password=").concat(password);
Type type = new TypeToken(){}.getType();
loginModel.login(url, new ICallBack() {
@Override
public void onSuccess(Object obj) {
iv.dissmiss();
iv.success(obj);
LoginBean loginBean = (LoginBean) obj;
if (loginBean.getCode().equals("0")){
iv.gotoMain();
}
SharedPreferences sp = iv.getContext().getSharedPreferences("config",Context.MODE_PRIVATE);
sp.edit().putString("mobile",mobile)
.putString("password",password)
.commit();
}
@Override
public void onFailed(Exception e) {
iv.dissmiss();
iv.failed(e);
}
},type);
}
}
